Abstract
The tunneling method for dental block grafting is surgical method for increasing the thickness of the soft tissue of the mouth prior to performing block grafting procedures for dental implants. The method includes cutting a pair of incisions in the mucosa. A tunnel is formed through the mucosa which extends between, and connects, the pair of incisions. The tunnel is then extended coronally to undermine tissue covering the recipient site. An acellular dermal matrix is then sutured to an exposed end of a dental implement pulled through the tunnel to position the acellular dermal matrix within the tunnel. The acellular dermal matrix is then positioned over the recipient site using a periosteal elevator, and the acellular dermal matrix is fixed coronally by suspension sutures. The pair of incisions are closed with interrupted sutures, and a block graft is fixed to the recipient site by a pair of titanium screws.
